As used herein, the terms “enhance” or “enhancing” when used to modify the terms “function” or “survival” means that the presence of a compound of the present invention has a positive effect on the function and/or survival of a trophic factor responsive cell compared with a cell in the absence of the compound. For example, and not by way of limitation, with respect to the survival of, e.g., a cholinergic neuron, a compound of the present invention would evidence enhancement of survival of a cholinergic neuronal population at risk of dying (due to, e.g., injury, a disease condition, a degenerative condition or natural progression) when compared to a cholinergic neuronal population not presented with such a compound, if the treated population has a comparatively greater period of functionality than the non-treated population. As a further example, and again not by way of limitation, with respect to the function of, e.g., a sensory neuron, a compound of the present invention would evidence enhancement of the function (e.g. neurite extension) of a sensory neuronal population when compared to a sensory neuronal population not presented with such a compound, if the neurite extension of the treated population is comparatively greater than the neurite extension of the non-treated population.

As used herein, the terms “inhibit” or “inhibition” refer to a specified response of a designated material (e.g., enzymatic activity) is comparatively decreased in the presence of a compound of the present invention.

As used herein, the terms “cancer” or “cancerous” refer to any malignant proliferation of cells in a mammal. Examples include prostate, benign prostate hyperplasia, ovarian, breast, brain, lung, pancreatic, colorectal, gastric, stomach, solid tumors, head and neck, neuroblastoma, renal cell carcinoma, lymphoma, leukemia, other recognized malignancies of the hematopoietic systems, and other recognized cancers.

As used herein the terms “neuron”, “cell of neuronal lineage” and “neuronal cell” refer to a heterogeneous population of neuronal types having singular or multiple transmitters and/or singular or multiple functions; preferably, these are cholinergic and sensory neurons. As used herein, the phrase “cholinergic neuron” means neurons of the Central Nervous System (CNS) and Peripheral Nervous System (PNS) whose neurotransmitter is acetylcholine; exemplary are basal forebrain and spinal cord neurons. As used herein, the phrase “sensory neuron” includes neurons responsive to environmental cues (e.g., temperature, movement) from, e.g., skin, muscle and joints; exemplary is a neuron from the DRG.

As used herein the term “trophic factor” refers to a molecule that directly or indirectly affects the survival or function of a trophic factor responsive cell. Exemplary trophic factors include Ciliary Neurotrophic Factor (CNTF), basic Fibroblast Growth Factor (bFGF), insulin and insulin-like growth factors (e.g., IGF-I, IGF-II, IGF-III), interferons, interleukins, cytokines, and the neurotrophins, including Nerve Growth Factor (NGF), Neurotrophin-3 (NT-3), Neurotrophin-4/5 (NT-4/5) and Brain Derived Neurotrophic Factor (BDNF).

As used herein the term “trophic factor-responsive cell” refers to a cell which includes a receptor to which a trophic factor can specifically bind; examples include neurons (e.g., cholinergic and sensory neurons) and non-neuronal cells (e.g., monocytes and neoplastic cells).

As used herein the terms “trophic factor activity” and “trophic factor-induced activity”, refer to both endogenous and exogenous trophic factors, where “endogenous” refers to a trophic factor normally present and “exogenous” refers to a trophic factor added to a system. As defined, “trophic factor induced activity” includes activity induced by (1) endogenous trophic factors; (2) exogenous trophic factors; and (3) a combination of endogenous and exogenous trophic factors.

As used herein, the term “at risk of dying” in conjunction with a biological material, e.g., a cell such as a neuron, refers to a state or condition which negatively impacts the biological material such that the material has an increased likelihood of dying due to such state or condition. For example, compounds disclosed herein can “rescue” or enhance the survival of motoneurons which are naturally at risk of dying in an in ovo model of programmed cell death. Similarly, for example, a neuron may be at risk of dying due to the natural aging process which occasions the death of a neuron, or due to an injury, such as a trauma to the head, which may be such that neurons and/or glia, for example, impacted by such trauma may be at risk of dying. Further, for example, a neuron may be at risk of dying due to a disease state or condition, as in the case of neurons at risk of dying as occasioned by the disease ALS. Thus, by enhancing the survival of a cell at risk of dying by use of a compound of the claimed invention is meant that such compound decreases or prevents the risk of the death of the cell.

As used herein the term “contacting” refers to directly or indirectly causing placement together of moieties, such that the moieties directly or indirectly come into physical association with each other, whereby a desired outcome is achieved. Thus, as used herein, one can “contact” a target cell with a compound as disclosed herein even though the compound and cell do not necessarily physically join together (as, for example, is the case where a ligand and a receptor physically join together), as long as the desired outcome is achieved (e.g., enhancement of the survival of the cell). Contacting thus includes acts such as placing moieties together in a container (e.g., adding a compound as disclosed herein to a container comprising cells for in vitro studies) as well as administration of the compound to a target entity (e.g., injecting a compound as disclosed herein into a laboratory animal for in vivo testing, or into a human for therapy or treatment purposes).

As used herein, a “therapeutically effective amount” refers to an amount of a compound of the present invention effective to prevent or treat the symptoms of a particular disorder.

As used herein, the term “subject” refers to a warm blooded animal such as a mammal, preferably a human, or a human child, which is afflicted with, or has the potential to be afflicted with one or more diseases and conditions described herein.

As used herein, the term “pharmaceutically acceptable” refers to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem complications commensurate with a reasonable benefit/risk ratio.

As used herein, “pharmaceutically acceptable salts” refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.

The pharmaceutically acceptable salts of the present invention can be prepared from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two. Generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418, the disclosure of which is hereby incorporated by reference.

As used herein, the term “unit dose” refers to a single dose which is capable of being administered to a patient, and which can be readily handled and packaged, remaining as a physically and chemically stable unit dose comprising either the active compound itself, or as a pharmaceutically acceptable composition, as described hereinafter.

As used herein, “prodrug” is intended to include any covalently bonded carriers which release the active parent compound as defined in the present invention in vivo when such prodrug is administered to a mammalian subject. Since prodrugs are known to enhance numerous desirable qualities of pharmaceuticals (e.g., solubility, bioavailability, manufacturing, etc.) the compounds of the present invention may be delivered in prodrug form. Thus, the present invention contemplates prodrugs of the claimed compounds, compositions containing the same, and methods of delivering the same. Prodrugs of a compound of the present invention may be prepared by modifying functional groups present in the compound in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compound. Accordingly, prodrugs include, for example, compounds of the present invention wherein a hydroxy, amino, or carboxy group is bonded to any group that, when the prodrug is administered to a mammalian subject, cleaves to form a free hydroxyl, free amino, or carboxylic acid, respectively. Examples include, but are not limited to, acetate, formate and benzoate derivatives of alcohol and amine functional groups; and alkyl, carbocyclic, aryl, and alkylaryl esters such as methyl, ethyl, propyl, iso-propyl, butyl, isobutyl, sec-butyl, tert-butyl, cyclopropyl, phenyl, benzyl, and phenethyl esters, and the like.

It is recognized that compounds of the present invention may exist in various stereoisomeric forms. As such, the compounds of the present invention include their respective diastereomers or enantiomers. The compounds are normally prepared as racemates and can conveniently be used as such, but individual diastereomers or enantiomers can be isolated or synthesized by conventional techniques if so desired. Such racemates and individual diastereomers or enantiomers and mixtures thereof form part of the present invention.

It is well known in the art how to prepare and isolate such optically active forms. Specific stereoisomers can be prepared by stereospecific synthesis using enantiomerically pure or enantiomerically enriched starting materials. The specific stereoisomers of either starting materials or products can be resolved and recovered by techniques known in the art, such as resolution of racemic forms, normal, reverse-phase, and chiral chromatography, recrystallization, enzymatic resolution, or fractional recrystallization of addition salts formed by reagents used for that purpose. Useful methods of resolving and recovering specific stereoisomers described in Eliel, E. L.; Wilen, S. H. Stereochemistry of Organic Compounds; Wiley: New York, 1994, and Jacques, J, et al. Enantiomers, Racemates, and Resolutions; Wiley: New York, 1981, each incorporated by reference herein in their entireties.

It is further recognized that functional groups present on the compounds of the present invention may contain protecting groups. For example, the amino acid side chain substituents of the compounds of the present invention can be substituted with protecting groups such as benzyloxycarbonyl or t-butoxycarbonyl groups. Protecting groups are known per se as chemical functional groups that can be selectively appended to and removed from functionalities, such as hydroxyl groups and carboxyl groups. These groups are present in a chemical compound to render such functionality inert to chemical reaction conditions to which the compound is exposed. Any of a variety of protecting groups may be employed with the present invention. Preferred groups for protecting lactams include silyl groups such as t-butyldimethylsilyl (“TBDMS”), dimethoxybenzhydryl (“DMB”), acyl, benzyl, and methoxybenzyl groups. Preferred groups for protecting hydroxy groups include TBS, acyl, benzyl (“Bn”), benzyloxycarbonyl (“CBZ”), t-butyloxycarbonyl (“Boc”), and methoxymethyl. Many other standard protecting groups employed by one skilled in the art can be found in Greene, T. W. and Wuts, P. G. M., “Protective Groups in Organic Synthesis” 2d. Ed., Wiley & Sons, 1991.

The general procedures to prepare the pyrrolocarbazoles of the present invention are described in U.S. Pat. Nos. 5,705,511 (“the '511 patent”) and 6,630,500, PCT Publ. No. WO 00/47583, J. Heterocyclic Chemistry, 2001, 38, 591, and J. Heterocyclic Chemistry, 2003, 40, 135. In general, the lactam nitrogen or intermediate alcohol groups of the intermediates outlined in Table B may be protected with such groups as acetyl, substituted silyl, benzyl, Boc, or dimethoxybenzhydrol.

Intermediate 1-23 (wherein R is hydrogen) used to prepare examples in Table 2, was prepared from the β-ketone, 2-methyl-1,4,6,7-tetrahydro-5H-indazol-5-one (Peet, N. P.; LeTourneau, M. E.; Heterocycles, 1991, 32, 41) using methods described in the '511 patent and in J. Heterocyclic Chemistry, 2003, 40, 135.

As shown in Scheme 1, the NI-methylpyrazole derivatives in Table 3 were prepared from the 1-methyl α-ketone (J. Chem. Res., 1986, 1401). The N2-methyl pyrazole intermediates were prepared according to procedures in J. Heterocyclic Chem. 1992, 19, 1355.

Scheme 2 outlines the route to prepare carbamate-type derivatives, such as Examples 1-2, and 70-72. An alternate method to preparing N,N-di-substituted carbamates utilized a nitrophenyl carbonate intermediate which may be treated with various primary or secondary amines. Similarly urea, O-carbamate, and N-carbamate derivatives may be prepared from reaction of the appropriate amine or phenol intermediate with an isocyanate or chloroformate or from the appropriate nitrophenyl carbonate, nitrophenyl carbamate, or trichloromethylcarbonyl (see J. Org. Chem. 2003, 68, 3733-3735).

Scheme 3 outlines a route to prepare heteroaryl ethers from the corresponding phenol using a base such as sodium hydride and a heteroaryl bromide or chloride.

Scheme 4 shows a route for the preparation of N-carbamates (examples 50-69) or amides (examples 74-82) from the corresponding aniline intermediates 1-29. Amino intermediates 1-29 were prepared by alkylation of the appropriate cyano-esters with the appropriate alkyl iodide or bromide followed by nitration, and subsequent RaNi reduction to provide the amino-lactam. The desired compounds were readily prepared from the amine.

Heteroaryl ketones may be prepared using standard Friedel-Crafts type acylation reactions.

General procedure C for Examples 145-156: To a well-stirred suspension of the CH₂OH intermediates I, II, or III in 7 mL of methylene chloride were added sequentially trifluoroacetic anhydride (5 equivalents) and N-methyl morpholine (5 eq) at 5° C. and under argon atmosphere. The resulted suspension was stirred at room temperature for 3 hours and the low boiling solvents were removed under vacuum. A stirred solution of this tritrifluoroacetate intermediate in an appropriate alcohol was heated to 80° C. for 6-48 hours in an oil bath. Gradually, the heterogeneous reaction mixture became homogeneous. When no starting material was observed by HPLC the reaction mixture was worked up by removing the solvent in vacuo. The residues was purified by either triturating with water or ether or alternatively, flash chromatography or preparative plate chromatography on silica gel using ethyl acetate or an ethyl acetate/hexane mixture.

The compounds of the present invention are useful, inter alia, as therapeutic agents. Particularly, the compounds are useful for kinase inhibition, such as, for example, trk, VEGFR, PDGFR, PKC, MLK, DLK, Tie-2, FLT-3, and CDK1-6. Various compounds of the present invention show enhanced pharmaceutical properties over those disclosed in the art and improved pharmacokinetic properties in mammals. The compounds of the present invention show enhanced pharmaceutical properties over those disclosed in the art, including increased MLK and DLK dual inhibition activity, or increased VEGFR and Tie-2 dual inhibition activity, along with improved pharmacokinetic properties in mammals.

In one embodiment, the present invention provides a method for treating or preventing diseases and disorders, such as those disclosed herein, which comprises administering to a subject in need of such treatment or prevention a therapeutically effective amount of a compound of the present invention.

In an additional embodiment, the present invention provides a method for inhibiting trk kinase activity comprising providing a compound of the present invention in an amount sufficient to result in effective inhibition. Particularly, inhibition of trk implies utility in, for example, diseases of the prostate such as prostate cancer and benign prostate hyperplasia, as well as for the treatment of inflammation, such as neurological inflammation and chronic arthritis inflammation. In a preferred embodiment, the trk kinase receptor is trk A.

The majority of cancers have an absolute requirement for angiogenesis, the process by which new blood vessels are formed. The most potent angiogenic cytokine is vascular endothelial growth factor (VEGF) and there has been substantial research into the development of VEGF/VEGF receptor (VEGFR) antagonists. Receptor tyrosine kinase (RTK) inhibitors could have broad spectrum antitumor activity in patients with advanced pre-treated breast and colorectal carcinoma and Kaposi's sarcoma. Potentially these agents may play a role in the treatment of both early (adjuvant) and advanced cancer. The importance of angiogenesis for the progressive growth and viability of solid tumors is well established. Emerging data suggest an involvement of angiogenesis in the pathophysiology of hematologic malignancies as well. Recently, authors have reported increased angiogenesis in the bone marrow of patients with acute myeloid leukemia (AML) and normalization of bone marrow microvessel density when patients achieved a complete remission (CR) after induction chemotherapy. Tumor angiogenesis depends on the expression of specific mediators that initiate a cascade of events leading to the formation of new microvessels. Among these, VEGF (vascular endothelial growth factor), FGF (fibroblast growth factor) play a pivotal role in the induction of neovascularization in solid tumors. These cytokines stimulate migration and proliferation of endothelial cells and induce angiogenesis in vivo. Recent data suggest an important role for these mediators in hematologic malignancies as well. Isolated AML blasts overexpress VEGF and VEGF receptor 2. Thus, the VEGF/VEGFR-2 pathway can promote the growth of leukemic blasts in an autocrine and paracrine manner. Therefore, neovascularization and angiogenic mediators/receptors may be promising targets for anti-angiogenic and anti-leukemic treatment strategies. Thus, in other embodiments, the present invention provides a method for treating or preventing angiogenic disorders where VEGFR kinase activity contributes to pathological conditions, the method comprising providing a compound of the present invention in an amount sufficient to result in the vascular endothelial growth factor receptor being contacted with an effective inhibitory amount of the compound. Inhibition of VEGFR implies utility in, for example, angiogenic disorders such as cancer of solid tumors, endometriosis, macular degeneration, retinopathy, diabetic retinopathy, psoriasis, hemangioblastoma, as well as other ocular diseases and cancers.

FLT3, a member of the receptor tyrosine kinase (RTK) class III, is preferentially expressed on the surface of a high proportion of acute myeloid leukemia (AML) and B-lineage acute lymphocytic leukemia (ALL) cells in addition to hematopoietic stem cells, brain, placenta and liver. An interaction of FLT3 and its ligand has been shown to play an important role in the survival, proliferation and differentiation of not only normal hematopoetic cells but also leukemia cells. Mutations of the FLT3 gene was first reported as an internal tandem duplication (ITD) of the juxtamembrane (JM) domain-coding sequence, subsequently as a missense mutation of D835 within a kinase domain. ITD- and D835-mutations are essentially found in AML and their frequencies are approximately 20 and 6% of adults with AML, respectively. Thus, mutation of the FLT3 gene is so far the most frequent genetic alteration reported to be involved in AML. Several large-scale studies in well-documented patients published to date have demonstrated that ITD-mutation is strongly associated with leukocytosis and a poor prognosis. An inhibitor compound of FLT3 tyrosine kinase have an application in treatment of leukemia. The present invention provides a method for treating disorders characterized by responsiveness to FLT3 inhibition, the method comprising providing a compound of the present invention in an amount sufficient to result in the inhibition of FLT3.

Platelet-derived growth factor (PDGF) was one of the first polypeptide growth factors identified that signals through a cell surface tyrosine kinase receptor (PDGF-R) to stimulate various cellular functions including growth, proliferation, and differentiation. Since then, several related genes have been identified constituting a family of ligands (primarily PDGF A and B) and their cognate receptors (PDGF-R alpha and beta). To date, PDGF expression has been shown in a number of different solid tumors, from glioblastomas to prostate carcinomas. In these various tumor types, the biologic role of PDGF signaling can vary from autocrine stimulation of cancer cell growth to more subtle paracrine interactions involving adjacent stroma and even angiogenesis. Thus, in additional embodiments, the present invention provides a method for treating or preventing disorders where PDGFR activity contributes to pathological conditions, the method comprising providing a compound of the present invention in an amount sufficient to result in the platelet derived growth factor receptor being contacted with an effective inhibitory amount of the compound. Inhibition of PDGFR implies utility in, for example, various forms of neoplasia, rheumatoid arthritis, chronic arthritis, pulmonary fibrosis, myelofibrosis, abnormal wound healing, diseases with cardiovascular end points, such as atherosclerosis, restenosis, post-angioplasty restenosis, and the like.

In further embodiments, the present invention provides a method for treating or preventing disorders where MLK activity contributes to pathological conditions, such as those listed above, wherein the method comprises providing a compound of the present invention in an amount sufficient to result in the MLK receptor being contacted with an effective inhibitory amount of the compound. Inhibition of MLK implies utility in, for example, forms of cancer where MLKs play a pathological role as well as in neurological disorders.

In still other embodiments, the present invention provides a method for treating disorders characterized by the aberrant activity of trophic factor responsive cells, the method comprising providing a compound of the present invention in an amount sufficient to result in the trophic factor cell receptor being contacted with an effective activity inducing amount of the compound. In certain preferred embodiments, the activity of the trophic factor responsive cells is ChAT activity.

Fibroblast growth factor receptors (FGFR) are members of a family of polypeptides synthesized by a variety of cell types during the processes of embryonic development and in adult tissues. FGFR have been detected in normal and malignant cells and are involved in biological events that include mitogenic and angiogenic activity with a consequent crucial role in cell differentiation and development. To activate signal transduction pathways, FGFR are coupled to fibroblast growth factors (FGF) and heparan sulfate (HS) proteoglycans to form a biologically fundamental ternary complex. Based on these considerations, inhibitors able to block the signaling cascade through a direct interaction with FGFR could have antiangiogenesis and subsequent antitumor activity. Accordingly, the present invention provides a method for treating disorders characterized by the aberrant activity of FGF responsive cells, the method comprising providing a compound of the present invention in an amount sufficient to result in the FGFR being contacted with an effective activity inducing amount of the compound.

The compounds of the present invention can also have positive effects on the function and survival of trophic factor responsive cells by promoting the survival of neurons. With respect to the survival of a cholinergic neuron, for example, the compound may preserve the survival of a cholinergic neuronal population at risk of dying (due to, e.g., injury, a disease condition, a degenerative condition or natural progression) when compared to a cholinergic neuronal population not presented with such compound, if the treated population has a comparatively greater period of functionality than the non-treated population.

A variety of neurological disorders are characterized by neuronal cells which are dying, injured, functionally compromised, undergoing axonal degeneration, at risk of dying, etc. These neurodegenerative diseases and disorders include, but are not limited to, Alzheimer's disease; motor neuron disorders (e.g. amyotrophic lateral sclerosis); Parkinson's disease; cerebrovascular disorders (e.g., stroke, ischemia); Huntington's disease; AIDS dementia; epilepsy; multiple sclerosis; peripheral neuropathies including diabetic neuropathy and chemotherapy induced peripheral neuropathy, AID related peripheral neuropathy; disorders induced by excitatory amino acids; and disorders associated with concussive or penetrating injuries of the brain or spinal cord.

In other preferred embodiments, the compounds of the present invention are useful for treating or preventing multiple myeloma and leukemias including, but not limited to, acute myelogenous leukemia, chronic myelogenous leukemia, acute lymphocytic leukemia, and chronic lymphocytic leukemia.

In additional embodiments, the present compounds are also useful in the treatment of disorders associated with decreased ChAT activity or the death, injury to spinal cord motoneurons, and also have utility in, for example, diseases associated with apoptotic cell death of the central and peripheral nervous system, immune system and in inflammatory diseases. ChAT catalyzes the synthesis of the neurotransmitter acetylcholine, and it is considered an enzymatic marker for a functional cholinergic neuron. A functional neuron is also capable of survival. Neuron survival is assayed by quantification of the specific uptake and enzymatic conversion of a dye (e.g., calcein AM) by living neurons. The compounds described herein may also find utility in the treatment of disease states involving malignant cell proliferation, such as many cancers.

The compounds of the present invention have important functional pharmacological activities which find utility in a variety of settings, including both research and therapeutic arenas. For ease of presentation, and in order not to limit the range of utilities for which these compounds can be characterized, the activities of the compounds of the present invention can be generally described as follows:

A. Inhibition of enzymatic activity

B. Effect on the function and/or survival of trophic factor responsive cells

C. Inhibition of inflammation-associated responses

D. Inhibition of cell growth associated with hyperproliferative states

E. Inhibition of developmentally programmed motoneuron death

Inhibition of enzymatic activity can be determined using, for example, VEGFR inhibition (e.g., VEGFR2 inhibition), MLK inhibition (e.g., MLK1, MLK2 or MLK3 inhibition), PDGFR kinase inhibition, NGF-stimulated trk phosphorylation, PKC inhibition, or trk tyrosine kinase inhibition assays. Effect on the function and/or survival of trophic factor responsive cells, e.g., cells of a neuronal lineage, can be established using any of the following assays: (1) cultured spinal cord choline acetyltransferase (“ChAT”) assay; (2) cultured dorsal root ganglion (“DRG”) neurite extension assay; (3) cultured basal forebrain neuron (“BFN”) ChAT activity assay. Inhibition of inflammation-associated response can be established using an indoleamine 2,3-dioxygenase (“IDO”) mRNA assay. Inhibition of cell growth associated with hyperproliferative states can be determined by measuring the growth of cell lines of interest, such as an AT2 line in the case of prostate cancer. Inhibition of developmentally programmed motoneuron death can be assessed in ovo using embryonic chick somatic motoneurons, which cells undergo naturally occurring death between embryonic days 6 and 10, and analyzing inhibition of such naturally occurring cell death as mediated by the compounds disclosed herein.

The inhibition of enzymatic activity by the compounds of the present invention can be determined using, for example, the following assays:

A description of assays that may be used in connection with the present invention are set forth below. They are not intended, nor are they to be construed, as limiting the scope of the disclosure.

Inhibition of trkA Tyrosine Kinase Activity

Selected compounds of the present invention were tested for their ability to inhibit the kinase activity of baculovirus-expressed human trkA cytoplasmic domain using an ELISA-based assay as previously described (Angeles et al., Anal. Biochem. 236: 49-55, 1996). Briefly, the 96-well microtiter plate was coated with substrate solution (recombinant human phospholipase C-γl/glutathione S-transferase fusion protein (Rotin et al., EMBO J., 11: 559-567, 1992). Inhibition studies were performed in 100 μl assay mixtures containing 50 mM Hepes, pH 7.4, 40 μM ATP, 10 mM MnCl₂, 0.1% BSA, 2% DMSO, and various concentrations of inhibitor. The reaction was initiated by addition of trkA kinase and allowed to proceed for 15 minutes at 37° C. An antibody to phosphotyrosine (UBI) was then added, followed by a secondary enzyme-conjugated antibody, alkaline phosphatase-labelled goat anti-mouse IgG (Bio-Rad). The activity of the bound enzyme was measured via an amplified detection system (Gibco-BRL). Inhibition data were analyzed using the sigmoidal dose-response (variable slope) equation in GraphPad Prism. The concentration that resulted in 50% inhibition of kinase activity is referred to as “IC₅₀”.

Inhibition of Vascular Endothelial Growth Factor Receptor Kinase Activity

Selected compounds of the present invention were examined for their inhibitory effects on the kinase activity of baculovirus-expressed VEGF receptor (human flk-1, KDR, VEGFR2) kinase domain using the procedure described for the trkA kinase ELISA assay described above. The kinase reaction mixture, consisting of 50 mM Hepes, pH 7.4, 40 μM ATP, 10 mM MnCl₂, 0.1% BSA, 2% DMSO, and various concentrations of inhibitor, was transferred to PLC-γ/GST-coated plates. VEGFR kinase was added and the reaction was allowed to proceed for 15 min. at 37° C. Detection of phosphorylated product was accomplished by addition of anti-phosphotyrosine antibody (UBI). A secondary enzyme-conjugated antibody was delivered to capture the antibody-phosphorylated PLC-γ/GST complex. The activity of the bound enzyme was measured via an amplified detection system (Gibco-BRL). Inhibition data were analyzed using the sigmoidal dose-response (variable slope) equation in GraphPad Prism.

Inhibition of Mixed Lineage Kinase-1 Activity

The kinase activity of MLK1 was assessed using the Millipore Multiscreen TCA “in-plate” format as described for protein kinase C (Pitt & Lee, J. Biomol. Screening, 1: 47-51, 1996). Briefly, each 50-μl assay mixture contained 20 mM Hepes, pH 7.0, 1 mM EGTA, 10 mM MgCl₂, 1 mM DTT, 25 mM β-glycerophosphate, 60 μM ATP, 0.25 μCi [γ-³²P]ATP, 0.1% BSA, 500 μg/ml myelin basic protein (UBI #13-104), 2% DMSO, 1 μM of test compound, and 1 μg/ml of baculoviral GST-MLK1_(KD). Samples were incubated for 15 min at 37° C. The reaction was stopped by adding ice cold 50% TCA and the proteins were allowed to precipitate for 30 min at 4° C. The plates were then washed with ice cold 25% TCA. Supermix scintillation cocktail was added, and the plates were allowed to equilibrate for 1-2 hours prior to counting using the Wallace MicroBeta 1450 PLUS scintillation counter.

Dual Leucine Zipper Bearing Kinase Assay

Compounds were tested for their ability to inhibit the kinase activity of recombinant baculoviral human DLK, containing the kinase domain and leucine zipper. Activity was measured in 384-well FluoroNunc plates (Cat#460372) using a time-resolved fluorescence readout (PerkinElmer Application Note 1234-968). Plates were coated with 30 μl of the protein substrate MKK7 (Merritt et al. 1999) at a concentration of 20 μg/ml in Tris buffered saline (TBS). Each 30 μl assay contained 20 mM MOPS (pH 7.2), 15 mM MgCl₂, 0.1 mM Na₃VO₄, 1 mM DTT, 5 mM EGTA, 25 mM β-glycerophosphate, 0.1% BSA, 100 μM ATP, and 2.5% DMSO. Reactions were started by the addition of 10 ng/ml GST-hDLK_(KD/LZ). For IC₅₀ determinations, a 10-point dose response curve was generated for each compound. Plates were incubated at 37° C. for 30 minutes, and the reactions stopped by the addition of 100 mM EDTA. Product was detected using Europium-labeled anti-phosphothreonine (Wallac#AD0093; diluted 1:10000 in 3% BSA/T-TBS). Following overnight capture at 4° C., 50 μl enhancement solution (Wallac #1244-105) was added and the plate gently agitated for 5 min. The fluorescence of the resulting solution was then measured using the time-resolved fluorescence (TRF) mode in the Multilabel Reader (Victor2 Model # 1420-018 or Envision Model # 2100). Inhibition data was analyzed using GraphPad PRISM. See also Merritt, S. E., Mata, M., Nihalani, D., Zhu, C., Hu, X., and Holzman, L. B. (1999) The Mixed Lineage Kinase DLK utilizes MKK7 and not MKK4 as Substrate. J. Biol. Chem. 274, 10195-10202.

Tie-2 Tyrosine Kinase Assay

Compounds were tested for their ability to inhibit the kinase activity of recombinant baculoviral human His₆-Tie2 cytoplasmic domain using a modification of the ELISA described for trkA (Angeles et al., 1996). A 384-well plate format was used for single-point screening while IC₅₀s were performed on 96-well plates. For single-point screening, each barcoded 384-well Costar High Binding plate (Cat # 3703) was coated with 50 μl/well of 10 μg/ml substrate solution (recombinant human GST-PLC-γ; Rotin et al., 1992) in Tris-buffered saline (TBS). The Tie2 activity was measured in 50-μl assay mixtures containing 50 mM HEPES (pH 7.2), 40 μM ATP, 10 mM MnCl₂, 2.5% DMSO, 0.05% BSA, and 200 ng/ml His6-Tie2_(CD). For IC₅₀ determinations, the assays were run as described above but in 96-well Costar High Binding plates (Cat # 3703) and with the volumes doubled. A 10-point dose response curve was generated for each compound. The kinase reaction was allowed to proceed at 37° C. for 20 minutes. The detection antibody, N1-Eu anti-phosphotyrosine (PT66) antibody (Wallac #AD0041), was added at 1:2000 diluted in block buffer [3% BSA in TBS with 0.05% Tween-20 (TBST)]. After one-hour incubation at 37° C., 50 μl of enhancement solution (Wallac #1244-105) was added and the plate was gently agitated. The fluorescence of the resulting solution was then measured using the time-resolved fluorescence (TRF) mode in the Multilabel Reader (Victor2 Model # 1420-018 or Envision Model # 2100). Inhibition data were analyzed using ActivityBase and IC₅₀ curves were generated using XLFit. The cited references are as follows:
